Product Overview
VIPERGAN50TR is an advanced quasi-resonant offline high-voltage converter with E-mode GaN HEMT. It is designed for medium power quasi-resonant ZVS (zero voltage switching at switch turn-on) flyback converters, capable of providing an output power of up to 50W in a wide range. It integrates a complete set of features that provide an extremely flexible and easy-to-use chip and helps to design a highly efficient offline power supply. The ZVS quasi-resonant operation with the dynamic blanking time feature and the valley synchronization function, which turns on the power switch always at the valley of the drain resonance, reduces the switching losses and maximizes the overall efficiency at any input line and load condition. The feed-forward compensation minimizes the maximum output peak power variation over the entire input voltage range. Typical applications are high efficiency power adapters, fast battery chargers, auxiliary power supply for appliances, industrial, consumers, lighting.
- Quasi-resonant (QR) flyback controller, 650 V E-mode power GaN transistor
- Embedded sense FET, valley-lock to ensure constant valley skipping
- Advanced power management for less than 30mW standby power consumption with adaptive burst-mode
- Output OVP protection, input OVP protection
- Input voltage feed-forward compensation for mains independent OPP variation
- Brown-in and brown-out protection
- Embedded thermal shutdown, frequency jitter for EMI suppression
- QFN narrow package
- Junction temperature range from -40 to 150°C
- Quiescent current is 900µA maximum (burst-mode operation)
